Respuesta :
Sarah's income = Number of trays × Rate per tray
y = 450 × 8
If there is an increase of 0.85 in price,
New price = 8 + 0.85
For x number of increases,
new price = 8 + 0.85x.
Number of trays reduced = 450 - 15x.
So, Sarah's income in this case is y = (450 - 15x) (8 + 0.85x).
Answer:
y=-12.75x^2+262.5x+3,600
